PADLOCK.

SPECIFICATION forming page of Letters Patent Nvaeee, dateulzrun 2, 1903. Application filed ,Ianuary 30, 1901. Serial No.45f327.. (No model.)

Be it known that I, ALBERTA. PACE, of the town of East Haven, county of New Haven, State of Connecticut, have invented a new and useful. Improvement in Padlocks, of which the following is a full, clearand exact description, when taken in connection with the accompanying drawings, which form a part thereof, and in which Figure l represents an` elevation of a padlock embodying my invention; Fig. 2, a central vertical section through the same; Fig. 3, a top view of the outer shell or casing; Figs. A and 5, top and side views, respectively, of the inner casing'or support; and Fi g, (l, a side view of the hasp, in detail.

In all figures similar letters of reference represent like parts.

This invention relates to padlocks, and has for its object the production of a novel, efti i cient, and'simple padlock embodying one or more of the improvements or combinations of parts set forth and claimed hereinafter.

Referring to the drawings, theparts designated by the letter A represent the outer casing or shell, open at its lower end and provided in its upper face with two circular openings a and a'.

B represents the hasp, the twolegs of which are adapted to fit into the openings d and a in the shell.

C is an inner casing or support for the cylindrical plug D and associated parts. The support C is provided at its lower end with a face-plate c, adapted when the support is in place within the shell A to close the lower end of the shell. An inwardly-projecting integral iiange E is located within the shell beneath the opening a, which iiange is provided with a slot or hole e fort-he screw, adapted to be screwed into a hole c inthe support C, thus holding the support and shell together. Access to the screw c is obviouslyimpossible while the hasp is forcedhome andthe shorter leg thereof projects into the opening a. fithin the support C, beneath the opening a of the shell A, is a tubular socket F for the longer leg of the hasp B. Vithin the socket is a coiled spring f, bearing against the lower end of the leg of the hasp or against a shoulder thereof, constantly tending to force the hasp outward. An annular groove G is formed about the longer leg of the hasp, near its end, and from the upper side of the groove a portion of theinner face `of the leg is cut away to form a longitudinal groove g. A springpressed pin I-I fits into a socket I in the support C on the inner side of the tubular socket F. The pin II is constantlypressed outward by the spring h within the socket I. To originallyinsert the hasp, thepin isforced back into its socket I so that its outer end is flush with the inner wall of the tubular socket F, whereupon the longer leg of the hasp is forced inward untilthe pin H comesropposite to the groove Gfor slot g, when 'the spring h will force it outward to engage therein and to prevent the removal of the hasp. As the pin is located on the inner side of the hasp, it is inaccessible from the outside of the casing, and therefore cannot be tampered with.

As the hasp is forced home, as shown in Fig. 2, the pin H moves along the longitudinal slot g, b ut when` the hasp is forced outward by thespringf the pin I-I travels along the slot ginthe opposite direction and permits the hasp to be turnedwhile it engages `in the annular groove G.

The cylindrical plug D is held in place by means of a washer K at its inner end, which end is also provided witha bit M, having two engaging ends fm andm', adapted to engage in the slots N and n in the two legs of the hasp, thus making' a double engagement therewith.

A washer O secures the bit M to the plug D by meansof screws o, Fig. 4. The plug is provided with the usualtumblers P and the usual tumblerbolts Q, sliding in suitable sockets q within the support C. Within the sockets q are also `located springs R for operating. the tumbler-bolts in well-known manner. A 4spring SV tends to keep the bit M in its normal position.A

Having now described my invention, which may vary somewhat in its details without de parting from the spirit thereof, what I claim, and desire to secure by Letters Patent, is-

1. In a padlock, the combination with a hasp; of a casing or shell having hasp-openings at one end; a support adapted to be i11- serted in said casing at the end thereof oppo- IOO site said hasp-openings a socket in said snpport registering with one of said hasp-openings, and in which one leg of said hasp is adapted to be permanently secured; an engagement between said shell and said support located Within said shell and accessible through the other hasp-o'pening While said leg of said hasp is secured in the socket of said support, but inaccessible when both legs of said hasp are locked in said support; and means for locking said hasp to said support, substantially as described.

2. In a padlock, the combination with a hasp; of a casing or shell having hasp-openings at `one end and an opening for a support in the opposite end; a separate support adapted to be inserted in said casing at the end opposite said hasp-openings; a socket in said support registering with one of said `projecting into said socket to engage said hasp to permit it limited longitudinal and free rotary movement; and a spring yieldingly holding said pin in such engagement, substantially as described.

In Witness whereof I have hereunto set my hand this 24th day of January, 1901.
